Specification of Letters Patent.

Patented July 25, 1911.

Original application filed November 1, 1899, Serial No. 735,449. Dividedand this application filed Lune 12,

To all whom it may concern:

Be it known that I, ALBERT I-I. ELLIS, citizen of the United States, andresident of Brielle, in the county of Monmouth and State of New Jersey,have invented certain new and useful Improvements in CombinedType-IVriting and Adding Machines, of which the following is aspecification.

My invention relates to combined typewriting and adding machines, and ithas for 7 its principal object to provide adding mechanism arranged tobe operated in conjunction with typewriting mechanism in such a manneras to add automatically numbers written by said typewriting mechanism,and including connections adjustable to locate the adding column orfield at diiferent positions widthwise of the paper.

The present case is a division of my prior application filed November1st, 1899, Serial No. 735,449. In said prior application the connectionsfrom the typewriter to the adding machine, are shown in two forms, andsaid prior application contains claims specific to one of said forms aswell as claims broad enough to cover both forms. The present applicationis limited to the one of said forms of connection not specificallyclaimed in the parent case.

My invention consists in certain features of construction andcombinations and ar rangemen'ts of parts, all of which will be fully setforth herein and particularly pointed out in the claims.

In seeking to attain the specific objects of my invention, I haveprovided electric connections between the writing mechanism and theadding mechanism, but some of the features of the invention will also befound useful in cases where the writing mechanism is mechanicallyconnected to the adding mechanism. Moreover, in pursuing said ob ject Ihave devised contrivances and combinations, mechanical as well aselectrical, which will be found useful in machines whose constructionvaries from mine in other respects. Y

Typewriting machines are usually provided with a series of keys, each ofwhich is connected to one or more types in'such a manner that thedepression of. any key causes its appropriate type to strike against thepaper. These types are sometimes mounted on type bars and sometimes on aSerial No. 632,632.

wheel or in other ways, As far as my invention is concerned, it isimmaterial in what manner the types are connected to the keys.Typewriting machines also usually have some part which moves stepby-s'tep as the several keys are actuated in order to cause the types tostrike the paper one after another a suitable distance apart. In sometypewritingmachines a paper carriage has this step-by-stepmovement andin others, as in most book typewriters, the paper is stationary and thetype action travels over the paper. Whatever partof the machine it isthat has this step-by-step motion, I shall call the carriage. In thepresent instance I have shown my invention applied to a Remingtontypewriter in which the types are mounted on pivoted type bars and inwhich the paper carriage is movable stepby-step.

The adding attachment may be, and preferably is, entirely disconnectedmechanically from the writing machine, but since it operateselectrically, it is connected with the machine by electric conductors,whichmay be flexible or rigid as-desirable. The only apparatus necessaryfor direct attachment to the typewriter, is such as is required forcompleting the electric circuits, and this is extremely simple.

In making out bills, waybills, manifests, statements, or records of anycharacter containing columns of figures to be added, when a numeral isprinted in either the units, tens, hundreds or. other column, the saidnumeral will be automatically as units, tens, hundreds, etc.,'accordingtothe column in which the .numeral is printed, 'so that thetotal will show upon the face of the adding machine and may be copiedtherefrom at the foot of the column. v

In carrying out my invention I prefer to use the ordinary figure keys'ofthe typewriter keyboard, and to provide for printing with these keys onall portions of a line.

or page, except 'the column or columns to be added, without affectingthe adding mechnism; but as soon as the paper is struck by the figuretypes in a figure column, the adding mechanism operates. For thispurpose two sets ofcircuit controllers on the typewriter are used, that'is' to 'say, each circuit connecting the typewriter with the 'addingmechanism contains two circuit con- I with reference to the accompanyingdrawings, in which Figure 1 is a conventional representation of theapparatus and circuits forming a part of or directly connected with at-ypewriting machine, in accordance with my invention. Fig. 2 is asimilar representation of the adding mechanism, and is to be read inconnection with Fig. 1. Fig. 3 is a front elevation of the addingmachine, the casing being in section. Fig. 4 is an end elevation of the'same with parts broken away. Fig. 5 is a front elevation of the addingmachine on a reduced scale. Fig. 6 is a section through a portion of themain shaft of the adding machine and its countershaft. Fig. 7 is a frontelevation of the countershaftof the adding machine and its connections.Fig. 8 is a plan of the stop bars. Fig. 9 is an end elevation of thefragment of carriage mechanismand the column gage shown at Fig. 1. Fig.10 is a side view of a typewriter key, showing a circuit controllerconnected thereto. Fig. 11 is a longitudinal vertical section of atypewriting machine provided with electrical devices in accordance withmy invention.

Referring first to Figs. 1, 9, 10 and 11, illustrating the apparatusconnected directly with the typewriter, the figure keys a, from 1 to 9inclusive, each operates a circuit controller consisting of contactplates a and a The plates a are electrically connected in series withone another in the circuit 1. The contact plates a are the respectiveterminals of nine wires numbered from 9 to '17 inclusive, and extendingto the adding wheel mechanism through a flexible cable or otherwise.Fixed to the paper carriage frame A of the typewriter are a block I) anda clamping plate 6 holding between them a series of metallic pins 6which stand vertically and with their lower ends exposed and on a level.These pins are the terminals of aseries of wires 2 to 8 inclusive, alsoextending to the adding wheel mechanism through a'fiexible cable orotherwise. 0 indicates a guiding rail or track which is secured to thetypewriter frame,

' p as by arms A secured by screws A to in front of which index A moves.

front corner-posts A of the framework A of the typewriter, adjacent tothe scale A this rail 0 is a slide 0 provided with a set Upon screw 0 bywhich itsposition on the rail may be fixed, and carrying a contactfinger 0 adapted to make contact with the lower ends of the pins 6 whenin the traverse of the paper-carriage they are carried over the finger;the slide also is provided with a short section of scale 0 having thesame divisions as the scale in front of which the index plays, andhaving as many divisions as there are pins 6 The slide 0 may be set atany position in front of the scale of the machine, and its position,obviously, will determine at what location in the line of writing thecircuits of the series 2 to 8 will be closed by the finger 0 The device0 with its appurtenances may therefore be termed an adding-column gage.The finger c is the terminal of wire 1, which, as before stated, leadsto each of the contact plates a beneath the keys. As usual, the carriageis provided-with a letter-spacing rack, A, with which engageescapementdogs A and A which rock upon an axisA", and are provided witha forwardly extending operating arm A, from which is suspended, by rodsA, a universal bar A, arranged beneath and transversely of key levers ATo each key lever is connected, by a rod A a type bar A, the type barsbeing radially arranged about a common printing center, and a platen Abeing mounted upon the carriage .over the common printing center. Suchtype-bars as are connected to the keys a bear figure types,- and theother type bars or shelf or other support adjacent thereto,

since preferably they are connected to the writing machine only throughelectrical conductors 2 to 17 which may be arranged in .a single cable.The adding mechanism is contained in the casing E, the face of which isprovided with an opening 6 through which the totals may be seen.Immediately behind this opening 6 is a shaft 7", upon which are mountedadding disks or wheels g, bearing upon their peripheries the figuresfrom zero to 9. The hub of each disk 9 carries a pinion f and a notchedwheel F, the latter being used to turn the adding disk when the nextdisk 9 to the right has completed a rotation- For this purpose each diskg is provided with a-tens-carrying pin i to en gage with a tens-carryingstar wheel f on a counter-shaft f there being one star wheel for eachdisk. The pin f strikes an arm of the star wheel f and forces it againstone causing the corresponding disk to move one point forward, therebyadding ten .units,

tens or -hundreds, etc;, as the case may be.

against a stop f -thereon, may be used, so that in case a star wheelshould be rotated by a notched wheel at a time when the parts are in theposition indicated at Fig.4, the succeeding tooth of the star wheel willlift the pawl and slip by-it, without imparting movement to the diskupon which the pawl is pivoted. The fixed pin f answers'for the'secondand third wheels from the left-hand end at Fig. 3, since the starwheels associated therewith are'never driven by the two left-handnotched wheels, as the latter are unprovided with independent actuatingmechanism.

The counter-shaft f is suspended from arms ff, pivoted upon an axis 7",said arms projecting beyond the axis and carrying a stop plate 7,normally standing adjacent to the peripheries of. the row of disks. Eachdisk is also provided with a peripheral pin or tappet f". Thecounter-shaft f is adapted to be swung backward by a rod f, to carry thestar wheels out of the range of movement of the pins F. The rod f passesthrough the front of the case and is there fitted. with a knob and acatch 7, by which an operator may at will throw the star wheels intoandlout of operative position. When the star wheels are thrust backward,the plate swings forward into the path ofmovement of tappets f"; andwhile the parts are in this position the crank i on the disk shaft may.be rotated,

and all of the disks turned together, until the tappets f are allstopped against the plate 7, in which position all of the disks showzero through the opening 6. By releasing knob f the stop plate f isremoved, and the star wheels swing forward again under the action ofspring 7' until collar f on rod f abuts against a fixed part of v thecasing, when the device is in position to again count from zero upward.The dlsks are spaced along the shaft f by means of friction washers fwhich are splined to the shaft. A compression spring f bearing at oneend against a collar f secured to the shaft, and at the other endagainst one of said washers, produces sufiicient friction between thewashers and the disks to insure the latter being rotated by the shaft atthe operation of crank f. An enlarged fricion disk or brake f is alsosplined to the shaft by means of a pin f, andbears against the innerside wall of the casing at f to prevent accidental rotation of theshaft.

Corresponding to the series of adding wheels is a series of verticallyarranged rack bars or drivers h adapted to engage with the pinionsf of{the respective adding wheel s, but normally disengaged therefrom.

Each rack bar is carried by bearings 2' attached to another bare, thelatter being hung upon parallel links 2' if, pivoted to the face plateof the casing.- A spring 2' swings the bars h and z' upward and forward,and so out of engagement with the corresponding adding wheel. The rackbars It all extend upward to a point near the top of the casing,adjacent to which is a push bar or actuator is, common to all the rackbars and pivoted to the casing at This actuator is adapted to be swungdownward by a solenoid magnet K, and afterward re turned to normalpositionby a spring 7: So long as the rack bars occupy their normal ordisengaged position, the actuator cannot affect them, but when any oneof them is thrown into engagement with its correspondin pinion, itsupper end assumes a position directly under the actuator, and if thelatter then operates against it, the rack bar is thrust downward untilit is stopped, during which movement it rotates its corresponding addingdisk. Upon the circuit which controls the magnet t being broken, thespring i swings the driver 1 it outof engagement with the pinion,whereupon the spring 7' elevates the rack to initial position. Theextent of rotation of a given disk determines the quantity added, sothat by arranging-to'stop the downward movement of the rack bar atvarious points, the quantity added at each operation can be controlled.I have provided such a stop ping arrangement in the lower part of thecasing of the adding machine. It consists of a series of stop bars Parranged one above the other in a suitable frame 7), wherein each bar isfree to slide independentlyin a longitudinal direction. Across the frontface of the gang of stop bars, a series of vertical grooves 10 is outimmediately be neath the ends of the drivers h. So long as tfiesegrooves or cutaways are unobstructed, te driver has free movement acrossthe face of the entire series of stop-bars, but when anyone of them islongitudinally displaced the grooves are closed by such displacement,and the drivers can only'travel across the face "of-the stop bars untilthey are'intercepted by the displaced stop bar. It will now beunderstood that by selecting a certain disk for rotation and a certain.stop bar for determining the extent of its rotation, any amount may becalculated .by

the machine. With each stop bar is connected a lever g pivoted at 9 andto this lever is attached an armature 9 in front of which is arranged anelectro-magnet; the

-' nine magnets are mounted upon a suitable bracket 9*, and are lettered'w, 20 10 etc. hen any one of these magnets is energized, thecorresponding lever g and stop bar P are moved, the stop bars beingreturned to their normal positions by springs r Adjacent to the oppositeends of the stop .bars are two metallic plates 1 and r suitablyinsulated from each other, and each having a projection o standing inthe path of movement of the stop bars. hen any stop bar is moved by itsmagnet, it contacts with one projection 1 on each of the two plates 0"and W, and closes a circuit which is traced by wires 18 and 19 leadingthrough the solenoid K and the battery G.

In operation, the slide or column gage 0 is adjusted along the rail 0until the third division mark on its scale (counting from the left) isopposite the point on the machine scale where the decimal pointseparating the dollars and cents column occurs; after operating theletter keys to write the first item on the page, the carriage is movedto the left by the operation of the usual release key or spacing keyuntil the carriage index A} points to that division on the gage scale 0which corresponds to the position of the first figure of the amount tobe written. By reason of this adjustment of the column gage. thehundreds adding wheel (the fifth from the left at Figs. 2 and 3), is2111- tomatically coupled to all the figure keys at that point in theline of writing at which numerals in the hundreds column occur. Thus. if256.74 is the amount, the index A will be stopped at the sixth divisionof the slide scale from the left, at which point the contact finger 0will be against the fifth full line pin 5 counting from the right,thereby coupling the magnet 27* to all the figure keys, andsimultaneously enabling any chosen key to energize the correspondingstop-operating magnet. Then the figure keys for 2, 5 and 6 are struck insuccession, then the period key, and then the figure keys for 7 and 4.When key for the numeral 2 is depressed, the lever A swings downwardly,and by means of the connecting rod A swings the rear typebar having thetype 2 thereon up against the paper on the platen, so that the numeral 2is imprinted upon the paper. At the same time the universal bar A iscarried down by the key lever, and the initial movement of the spacingdogs is effected in a wellknown manner through the rods A and the rockerA all as indicated by dotted lines at Fig. 11. The key lever alsocarries down the contact plate a, so that it touches the contact platea, as also indicated by dotted lines, whereby a circuit is closed fromthe key through wire 1, finger 0 wire 4, magnet 2f, wire 19, battery G,wires 20 and 21, magnet 10 wire 10, and back to key 2. The circuits ofall the other magnets 11: and t are open at the keyboard and carriage.The energizing of magnet t throws the fifth rack bar or driver it intoengagement with its pinion, and the energizing of magnet 10 displacesthe second stop bar. The stop bar in moving closes the circuit of thesolenoid K through wires 18 and 19, and the actuator is accordinglypulled downward, forcing the rack bar down until it is arrested by thedisplaced stop bar. The engagement of the rack and pinion rotates thefifth disk two points forward, showing the figure 2 at the hundredsposition, through the opening in front of the machine.

The moment the key is released, the key lever, type bar, universal barand feeding dogs, as well as the contact plate (1 resume their normalpositions and the carriage.

moves a letter space, so that the circuit traced above is broken at twoplaces by the rising of the key and the feeding of the paper carriage,whereupon the several magnets become deenergized and the springs j, gand k return the parts to normal position. At the same time the movementof the paper carriage makes contact between the next pin and the finger0 thereby coupling the succeeding adding wheel to all the figure keys.Next, the numeral 5 key is struck, the type 5 is imprinted on the paper,and a circuit is closed through wire 1, finger a, wire 5, magnet t wire19, battery G, wire 20, magnet Q0 wire 13, and back to key 5. Thiseffects an operative connection between the fourth rack bar and itsadding wheel, and displaces the fifth stopv bar, whereupon the circuitof solenoid K is closed and the fourth disk rotated until its figure 5shows in the opening in front of the casing. In the same manner each ofthe figures in the amount of quantity is written. In writing the secondand succeeding numbers in the column, it is obvious that since the disksare constructed upon the usual plan of adding machines, they will show atotal through the opening in the casing corresponding to the'totalamount written by the machine at any given time. \Vhen the column hasbeen finished, the total amount shown by the adding machine may bewritten underneath the column, the hand switch or controller 3 havingbeen first shifted; or if the total is written in the next column to theright, as is often the'case, the switch a need not be operated since theposition of the gage 0 leaves the circuit in normal condition andprevents the further operation of the adding mechanism.

In Fig. 1 two of the pins 5 are shown in dotted lines. On-writingamounts of money,

or other amounts which it is desired to point off with commas orperiods, such characters may be written in at the places where theomitted pins occur, without affecting any of the circuits; thus, whilethe amount 256.7% occupies six spaces, only five of them are figurespaces, and only five disks of the addmg mechanism would be rotated inwriting it, the other space being occupied by the period, and the pinfor that space being omitted or shifted.

It will be understood that while I have described the circuit controlleras mounted partly upon the paper carriage, the term is intended tocomprehend anycarriage or connected part which is moved by the spacingdevices, or in the event of the invention being used as an addingmachine merely, any suitable step-by-step moving device.

The adding-wheels may be operated whenever the carriage is in positionfor writing the figures in the desired column, independ ently of anyother or further movements of the carriage, so that in the operation ofwriting and adding a column of figures it is only necessary that thecarriage shall move back and forth a distance equal to the width of thecolumn; While at any time, if desired, the carriage may move a longerdistance to enable the printing of words or other figures in connectionwith the adding column.

The provision of the scale along which the column gage may slide is ofgreat importance, as it enables said gage to be instantly and accuratelyset to position for enabling the carriage to properly connect the addingwheels to the figure keys, so that when the figures are printed on thepaper they are also added on the corresponding adding wheels, withoutliability of error or of failure of the adding wheels to act. The columngage can be set to any portion of the line of writing. At. all otherportions of the line, whether preceding or following the column gage,words may be written, or, if desired, columns of figures may be writtenwithout affecting the adding mechanism. The means for connecting theadding wheels to the figure keys are positively controlled by thecarriage, so that the wheels can be so engaged only one at a time, andonly in their proper order.

In carrying out my improvements it is not essential to follow theprecise details of construction herein set. forth, as many changes maybe made within the scope of the invention.

What I claim as new and desire to secure by Letters Patent, is
